The Length measurement tool places specialized markups that calculate a single, linear measurement. Length measurements can be given depth or a slope.
Before placing a measurement, it is recommended that you set the page scale for the document first. When trying to place a measurement on a page that does not have a page scale, you will be prompted to set the scale.
Go to Tools > Measure > Length or press SHIFT+The Length measurement mode is engaged. ALT+L.
- Alternatively, click Length on the Measurements panel.
Measurements can be taken in units different from those used to set the page scale. To change the units used for a specific measurement dimension, go to the Measurement Properties section of the Measurements panel and select the desired measurement units from the available dimension dropdown lists.
- Any or all of these can also be set from the Units dropdown menu on the Properties toolbar.
Note: When changes are made to one or more of these properties before placing the measurement, they will persist until a different action is initiated (for example, placing a different type of measurement). This makes placing several measurements with the same properties easier. Keep in mind that all of these properties can be changed for specific measurements after they are placed; see Tips below.
- On the document, click the end points of the desired length.
If the page scale has been set, a preview of key measurement values will appear in the lower-right corner of the drawing as you place measurements to help ensure precision. You can hide this preview window by clicking the X to its left. When minimized, the preview window is replaced with a measure icon; click this icon to recall the measurement values preview window. Note that you can hide and recall this preview window while placing a measurement.
- Hold down SHIFT to draw lines that are at horizontal, vertical, or 45° angles.
- Length measurement arrows will automatically position themselves inside the extension lines when there is enough room, otherwise they will automatically position themselves outside the extension lines.
- Several measurement properties can be changed after the measurement has been placed, including Subject, Label, units of measure, and any applicable optional dimensions like Slope or Depth. Click a measurement so it is active and go to the Measurement Properties section on the Measurements panel to view and change any of these for the selected markup.
You can add an action to nearly any markup. Simply right-click the markup and select Edit Action to open the Action dialog box.
Markups might present with one or more of several indicator icons alerting users of certain conditions or attachments. These icon indicators appear below the markup to the right (or, in the case of grouped markups, below and to the right of the group) and include:
Action: Indicates that an action has been defined for this markup. Clicking this icon triggers the action.
Capture: Indicates that the markup has an embedded media, typically an image or video. Clicking this icon opens a preview window showing the embedded media (or first piece of media, if multiple are embedded) and provides easy access to several useful tools.
Reply: Indicates the existence of one or more replies to the markup in the Markups list. Hovering over the icon previews the replies and clicking it opens the Markups list (if it's not already open) and jumps directly to the markup's entry there. Users can turn off the ability to see reply indicators in the View menu.
Select a markup to reveal its control handles. Each handle controls a different aspect of the markup's size and orientation.
To resize the markup or change its angle, click and drag the appropriate yellow handle. Hold down SHIFT while dragging to force the markup to a horizontal, vertical, or 45° angle.
To adjust the height of the markup, click and drag the middle (caption) control handle.
To move only the caption, click and drag it while holding down SHIFT. To return the caption to its default position, right-click it and select Reset Caption Position.
To move the entire markup together, click and drag a part of it other than the control handles.
To rotate the caption, click and drag the orange handle directly over it. By default, the markup is rotated in increments of 15°; to rotate in increments of 1°, hold down SHIFT while dragging.To return a rotated caption to its original position, right-click it and select Reset Caption Position.
- To rotate the caption 180°, right-click the markup and select Flip Text.
See Editing Markups for more information.
The appearance of the Length measurement is configurable, including its line and fill color, line width and style, opacity, and font characteristics for the caption.
To change the appearance of a Length measurement, select it and click the Properties panel.
Color: Sets the line color.
Fill Color: Controls the fill color of the endpoints.
Highlight: Makes the fill color and line transparent so underlying content shows through.
Opacity: Sets opacity level of the line and endpoints, from 0 (invisible) to 100 (opaque).
Line Width: Sets the line thickness in points. A setting of 0 effectively renders the line invisible.
Style: Determines the line pattern.
Start and End: Controls the appearance of the endpoints for each side of the line. The diagram below shows samples of each type of endpoint.
Each endpoint has an associated Scale that determines the size of the endpoint in relation to the Line Width. By default, it is set to Auto and will automatically adjust as the Line Width is changed.
Show Caption: Select to include caption text on the markup. Click Edit to choose which measurements to include.
Show Caption Leader Line: Select to show the leader line to the caption.
Font: Sets the font used for the selected text.
- The first region shows all fonts used in the currently selected text element.
- The second region lists the standard PDF fonts that are supported by all PDF viewers. These fonts do not need to be embedded in the PDF when used, thereby cutting down on file size.
- The third shows all other available fonts. When used, these fonts need to be embedded in the PDF.
Note: If you attempt to embed a font for which the viewing and editing permissions do not allow formatting, Revu will display a message indicating the font will not be embedded in the PDF.
Font parameters are retained in the PDF such that even if the original font is not embedded or on the viewer's workstation, a suitable representation of the font will be substituted.
Font Size: Sets the size of the font.
Text Color: Sets the color of text.
The Font Style settings control the formatting of the text. Options include Bold, Italic, Underline, Strikethrough, Superscript and Subscript. Generally, any combination of these styles can be applied to format the text.
